PHXI03:MOTION IN A STRAIGHT LINE

362332 A car is moving towards check post with velocity of \(54\,\,km{h^{ - 1}}\). When the car is at a distance of 400 \(m\) from the check post, the driver applies brakes which causes a deceleration of \(0.3 {~ms}^{-2}\). Find the distance of car from the check post for 2 minutes after applying the brakes.

362333 A particle starts its motion from rest under the action of a constant force. If the distance covered in first \(10\,s\,{\rm{is}}\,{s_1}\) and that covered in the first \(20\,s\,{\rm{is}}\,{s_2}\), then

1 \({s_2} = 2\,{s_1}\)
2 \({s_2} = 3\,{s_1}\)
3 \({s_2} = \,{s_1}\)
4 \({s_2} = 4\,{s_1}\)

362334 A particle start from rest with a velocity of \(10\,m{\rm{/}}s\) and moves with a constant acceleration till the velocity increases to \(100\,m{\rm{/}}s\). At an instant the acceleration is simultaneously reversed, what will be the velocity of the particle when it comes back to the starting point?
